OneJet has named Pittsburgh a “focus city” and plans to add daily flights to Hartford, Connecticut and four other cities. The carrier uses seven-passenger Hawker 400 jets to cater to business travelers. It launched service from Pittsburgh International Airport in May, with nonstop flights to Indianapolis and Milwaukee. At a news conference today, the company pledged to add nonstop flights to four still-to-be decided destinations later this year, and to hire about 40 pilots, mechanics and other workers in Pittsburgh. The airport has added 14 non-stop destinations in the last 13 months, meaning the airport now served 53 destinations with non-stop flights. Hartford will become the 54th once twice-daily flights begin May 9.
